Atomizing device and electronic cigarette having same

Abstract

An atomizing device of an electronic cigarette is provided. The atomizing device includes a screw sleeve and an electrode ring fixed in the screw sleeve. The screw sleeve includes a glass fiber core, a heating coil winding around the glass fiber core and a heating coil support. Each of two ends of the heating coil is respectively connected to a silver coated bare electrical wire. The heating coil support has a central through hole and two side wall through holes. The bare electrical wires respectively extend through the side wall through holes which are exposed to two ends of the heating coil support, then respectively in contact with the screw sleeve and the electrode ring. An electronic cigarette having the atomizing device is also disclosed.
